well i just figured i'd give yall some feedback on my 400 build, i am very pleased with it, it runs 13.90's at pueblo motorsports park with slicks and 4,11's its a stock crank and rods with tmeyer flat top pistons and stock heads with exhaust port work and mild port work on the intake side, roller rockers and a crane 133042 cam, damn thing idles smooth as a stock motor but pulls like a jet, it runs on regular unleaded gas with about 32 degrees of timing and gets about 17mpg with 3.50 gears in it, its in a 71 f=100 short bed, i will be putting another one together identical to it for my 78 4x4 i am so happy with it.

 

Sound like a very good combo. Yes thats a very good cam for the money. I am curious about what headers you are using?

 

i'm running a set of hedman elite series headers, they are 1-3/4 inch primary with a 3 inch collector

 

how much your tuck weight ? I have a formula for an approximate hp for 1/4 mile.

 

it weighed roughly 3700 lbs

 

Horsepower = weight X 0.4 X 1/4-mile mph
--------------------------
282
Estimating horsepower at the drags

 

missing 1/4 mile mph.Then divided by 282

 

that hp estimations are very close to rear wheel horse power, meaning you wont be able to tell the eaxact hp fpr the engine on the fly cuz you will need to calculate the drive train loss......

 

it was in one of my book
